Despite the gaping hole left in the royal family by Princess Diana's untimely death, most of them don't speak about her very often (with the obvious exceptions of Prince William and Prince Harry).

Sarah Ferguson would like to change that. The Duchess of York is back to talking about how she and Diana bonded, and she revealed that even during her daughter Princess Eugenie's royal wedding to Jack Brooksbank last month, Di was still top of mind.

"I thought of absent friends and family; of Diana — but she’s with me all the time. What I miss most is her tinkling laughter," Ferguson said in an interview with Daily Mail.

"Diana was my best friend and the funniest person I knew. She had such timing and wit. It was a total joy to be with her because we just laughed and enjoyed life so much, and I know she would have loved the wedding."

Their allegedly close friendship isn't exactly a shocker. As Harper's Bazaarrevealed back in 2007, the Duchess of York and Princess of Wales were actually fourth cousins. Even so though, things did not end on a good note between them before Diana passed away.

"I really miss Diana. I loved her so much," Ferguson told the outlet more than a decade ago. "Diana was one of the quickest wits I knew; nobody made me laugh like her. But because we were like siblings — actually, we were fourth cousins and our mothers, who went to school together, were also best friends — we rowed. And the saddest thing, at the end, we hadn't spoken for a year, though I never knew the reason, except that once Diana got something in her head ... I tried, wrote letters, thinking whatever happened didn't matter, let's sort it out. And I knew she'd come back. In fact, the day before she died she rang a friend of mine and said, 'Where's that Red? I want to talk to her.'"

Tragically, that was not in the cards.
